Addition of trichloromethyl radicals (generated from BrCCl3 or CCl4) to a variety of alkenes in the presence of hydrogen-atom donors has been explored. The use of phosphites as hydrogen-atom donors was shown to provide a mild, novel and technically clean approach to trichloroalkanes.

Polychloro compounds were added to olefins in the presence of semiconductor particles (TiO2 or CdS) under photoirradiation.The photoreaction without semiconductors afforded no adducts at all; however, loading of TiO2 with Ag, Cu, or Fe3O4 enhanced the yield of the photoaddition reaction even further.Semiconductors operate as catalysts for the one-electron injection into the polychloro compounds.The relative adsorptions of the polychloro compounds onto the semiconductor particles correlate with the yields of the adducts, while the half-wave reduction potentials of the polychlorides do not.This semiconductor-catalyzed reaction was selective to unfunctionalized olefins and to those bearing a functional group at a remote position.An alkyne furnished the product via further reduction following addition, i.e., 1,1,3-trichloro-1-heptene (7) from 1-hexyne and carbon tetrachloride.
